AN EXPERIMENTAL INVESTIGATION ON THE MECHANICAL PROPERTIES OF CONCRETE WITH GRADE M55 AND M60 BY PARTIAL REPLACEMENT WITH SILICA FUME

Abstract

-Green Concrete is homogenous an artificial mixture of cement, natural sand, coarse aggregate and water. Its achievement lies in its versatility as can be designed to withstand harvest environment while taking on the most inspiring forms. This study investigates the performance of concrete under influence of silica fume in terms of slump, compressive strength at 7days and 28 days, flexural strength of beam at 28 days and splitting tensile strength of Cylinder at 28 days respectively. Total number of specimens of cubes, cylinders and beams were 50, 30 and 30 respectively, which were casted for testing to study influence of Silica fume on concrete. These Concrete specimens were deep cured in water under normal atmospheric temperature. On the basis of result that Silica fume mix concrete was found to increase in all strength (Compressive, Flexural & Splitting Tensile strength) of various mix of concrete at all age when compared to normal concrete. Its use should be promoted for better performance as well as for environmental sustainability. A total ten mix (trial mix, control mix and variation mix) were prepared for M55 & M60 grade of concrete.
